APPARATUS FOR STEBILIZING OR COOLING LIQUIDS.

Specification of Letters Patent.

Patented July 11, rare.

Application filed February 24, 1915. Serial No. 10,209.

T 0 all whom it may concern:

Be it known that I, EDWARD OTTEN, a citizen of the United States of America, and

resident of the borough of Brooklyn, county 1 of Kings, and State of New York, have invented certain new and useful Improvements in Apparatus for sterilizing or Cooling Liquids, of which the following is a specification.

This invention relates to improvements in and relating to apparatus for cooling beer, milk, etc, and sterilizing milk or other such liquids, wherein the flow of the cooling medium is in a direction opposite to the flow of the liquid to be cooled.

An object of the invention is to provide in such an apparatus an increased cooling surface, over which the liquid flows in a constant film, and wherein expensive connections are dispensed with and a co1nparatively simple and more substantial construction is substituted for the same.

Another object is to provide a cooler in which there are no exposed joints nor sharp corners, wherein sediment may be accumulated, and which may be readily cleaned with an ordinary brush or the like, and kept in a thoroughly sanitary condition.

With these and other objects in view, my invention consists of the novel features, constructions and arrangement of parts, hereinafter more fully described and pointed out in the claims.

In the drawings, Figure 1 is a vertical section of my improved apparatus; and Fig. 2 is a side-elevation partly in section.

Similar reference characters indicate corresponding parts throughout the several views.

Referring to the drawings, and more particularly to Fig. 1 thereof, two or more cooling sections are provided, each comprising a series of perpendicularly disposed horizontal pipes 1 arranged one below the other in serpentine fashion, and spaced apart by a filling portion 2 secured between each pipe 1, and having concave surfaces, so that there is permitted a continuous and uniform flow of the liquid in a film over the pipes and filling portion. The pipes 1 are secured at each end into casings. 3 and 4 which follow the general serpentine outline of the pipes. The said pipes fit into openings or bores 5 in the walls of the casing counterbored so as to provide shoulders 6,

against which the ends of the pipes abut. Inwardly directed surrounding portions 25, inclined to the surface of the pipes, are provided along the said casings, surrounding the said openings 5, and secured to the pipes by means of wipe-joints or solid bronze joints of metallic fillings 26, so that there is provided a continuous cooling surface free from any sharp corners or angles in which sediment might accumulate or become lodged. The said casings are provided also with arched chambers 7 into which the ends of each pair of pipes are fitted and alternating in each of the casings, so that the cooling liquid passing first through the inlet opening 8 and into the pipes is directed from each pipe by means of the chambers into the next higher pipe, and soon to and out of the outlet opening 9 provided at the top of the casing, and preferably, but not necessarily, on the same side of the cooling section as the said inlet opening.

Threaded openings 10 are provided for each of the chambers 7 along the outer surface of the casing, into which plugs 11 are screwed, so that access may be had to any portion of the interior of the apparatus for cleaning the same. The liquid to be cooled is supplied to the surface of the pipes through a trough 12 arranged above the uppermost pipe, having its bottom 13 shaped to conform to the upper portion of the said pipe, and provided adjacent the bottom and at either side thereof with perforations 14 through which the liquid passes on to the surface of the pipes. Projecting downwardly from each of the casings 3 and 4 is a recessed flange 15, which fits and is secured by means of screws 16 to a correspondingly recessed flange 17 projecting upwardly from the casings of the lower set of pipes. When the liquid arrives at the lower end of the upper section, it is conducted along a vertical flange 18 into a trough 19 provided on the uppermost pipe of the lower section, and through perforations 21 there in to the surface of the cooling pipes, from which it is finally conducted to a suitable receiving trough 22. The cooled wort or other liquid is conducted off from the said trough by means of a pipe 23 to the fermenting tanks or other destination in the usual manner. The lower section of the pipes is supported by means of standards 24: secured to the casings thereof, or other suitable means small space, and which, due to the serpentine arrangement of the pipes, flows continu.-':

ously and with the least amount of resistance, thereby resulting in a more uniformly cooled and cleaner liquid. I I have illustrated and described a preferred and satisfactory form'pof my invention, but it is obvious that changes maybe made therein without departing from the spirit and scope thereofpas defined in'the appended claims-' I Z I claim: 1:6; I r 1.
